Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

making-payments scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Making Payments

A broad skill for preparing and initiating Newline transfers. For a narrower transfer-only flow, create-transfer may be sufficient.

Guardrails

  • Confirm with the user before calling create-newline-transfer.
  • Resolve names and emails to customer and account UIDs first.
  • Verify the initiating customer is active and KYC-approved before sending funds.
  • Transfers are asynchronous; initial status may be queued or pending.

Step 1 — Identify the Initiating Customer

If you have the UID:

get-customer  uid=<customer_uid>

Otherwise search first:

list-customers  (filter by first_name, last_name, email, external_uid, or pool_uid)

Record:

  • uidinitiating_customer_uid
  • status
  • kyc_status
  • pool_uids

Stop if the customer is not in a valid state to initiate payments.

Step 2 — Identify the Source Account

Inspect available synthetic accounts:

get-synthetic-accounts

If needed, drill into a known account:

get-synthetic-account  uid=<source_synthetic_account_uid>

Confirm:

  • the account belongs to the correct customer or pool
  • the account is active
  • the available balance is sufficient
  • the relevant payment rail details exist for the intended use

Step 3 — Identify the Destination Account

This server creates transfers between two synthetic accounts, so you need a destination_synthetic_account_uid.

To find one:

get-synthetic-accounts

If the destination belongs to another known customer, resolve them first:

list-customers
get-customer  uid=<destination_customer_uid>
get-synthetic-accounts

If no destination synthetic account exists yet, switch to new-account-setup or managing-users-and-accounts before proceeding.

Step 4 — Choose the Transfer Rail

Exactly one of these blocks must be supplied.

Wire

wire: {
  wire_instructions
}

Use for traditional wire transfers when the user provides routing instructions.

ACH

ach: {
  sec_code,
  service_processing,
  originator_name,
  company_id,
  prenote,
  entry_description,
  effective_entry_date,
  id_number
}
